4.2 Turning OFF the HE910
Turning off of the device can be done in two ways:
via AT command (see HE910 Software User Guide, AT#SHDN)
by tying low pin ON_OFF*
Either ways, the device issues a detach request to network informing that the device will not
be reachable any more.
To turn OFF the HE910 the pad ON_OFF* must be tied low for at least 2 seconds and then
released.
